Sulmet and other

[herechilychiky]

I,ve got a question about Sulmet, I have some here with a exp. date of 9/13- you think its ok for a couple more mo. or should I just pitch it?? oh also what about tetracycline soluble and vita./electro powder. Both have good dates and have been in the frig.
Trying to figure out if I need to start over this Spring. Thanks in advance..
